Strap for Seamaster Aqua Terra 150m Co-Axial 41.5 Day-Date Red Gold / Silver

The Omega Aqua Terra 231.50.42.22.02.001 has a lug width of 20 millimetres. It is essential to measure correctly from centre to centre of the lateral case lugs to ensure compatibility with aftermarket straps. No variant of this reference exists in 19 or 21 millimetres.

For the Red Gold Aqua Terra 231.50.42.22.02.001, we recommend alligator in cognac or dark brown tones, which creates a natural aesthetic dialogue with the warmth of gold. Vegetable-tanned calf is a premium alternative for those seeking a natural patina that ages over time. Black vulcanised rubber is a contemporary choice for intentional contrast.

The strap is changed by extracting the spring bars that connect the lugs to the case. Use a spring bar tool to gently compress the internal spring of the bar, then slide the bar out from the lug. Insert the new strap by aligning the holes with the lugs and reinsert the spring bar. To avoid damage to the case, it is preferable to seek assistance from a watchmaker.

Yes, perfectly compatible. Any strap with a 20mm lug width will fit your Aqua Terra without any issues. We recommend noble materials (alligator, shell cordovan, vegetable-tanned calf) that do not contradict the aesthetic value of the red gold timepiece. Milano Straps offers customisable online straps and bespoke services by appointment at Casati Milano.

The lifespan of a leather strap depends on quality, tanning method and use. High-quality vegetable-tanned alligator resists 3–5 years of daily wear before showing evident wear. Vegetable-tanned calf ages more rapidly (2–4 years) but develops a fascinating patina. Premium brands such as Casati Milano provide 18 months of coverage for manufacturing defects. Protecting the strap from moisture and UV rays significantly extends its useful life.
